vLookup ... help please

[sarahp]

Hi,

I made a mistake last time ....sorry

I have two separates excel workbooks ( not worksheets!!).

Workbook no 1 which has several columns : A ( XP numbers) to O

Workbook no 2 which has two columns : A ( XP numbers) and B ( DOI numbers)


PS: both workbooks have column A in common ( XP numbers)

I am trying to extract the data from the column B ( DOI numbers ) of workbook no 2 and insert them into workbook no 1 ONLY when the data from column A ( XP numbers) match !


Can anyone help me with the formula?
Step by step ...

Also it is possible to automatically repeat the same formula accross several other workbooks ?:

..... with Workbook no 3 and 4 and 5 ...etc ....( Identical to woorkbook no 2) : has two columns : A ( XP numbers) and B ( DOI numbers)

Many thanks

Sarah

A formula similar to this should work for you:

=IF(ISNA(VLOOKUP(A2,'C:\My Documents\[Book2.xls]Sheet1'!$A1:B1000,2,1)),"Not Found",VLOOKUP(A2,'C:\My Documents\[Book2.xls]Sheet1'!$A1:B1000,2,1))

Of course, adjust the path to the other workbook and the lookup range as needed.

I added the error trap of ISNA to return "Not Found" if the value in col. A is not found in the lookup range. Without this, #N/A would be returned for each value not found.
